DUMPINGl-CAR.

To all whom it may concern:

Be it known that I, ALBERT C; MURPHY, a citizen of the United States, and resident of New York, county of New York, and State of New York, have invented an Improvement in Dumping-Cars, of which the following is a specification.

The object of my invention is to provide a suitable construction of dumping ear having hinged side doors and operating mechanism therefor, whereby the tilting operation of the body will automatically cause' the door on the depending side to open into discharging position, and during the righting of the body into its normal horizontal position, and to provide in a dumping car, locking means which normally look the doors when the body is in the normal horizontal position and which automatically release the doors during the preliminary porbody so as positive opening of the doors, and yet Which will assist in holding the doors in locked position when the body is in its normal horizontal positions during the travel of the car, said means to have capacity for permitting the door releasing means to be adjusted out of automatic action whereby the latches may be released by hand operation in the dumping position where it is desired to discharge only a portion of the load, stood that when this provision is made the body is provided with a plurality of doors on its side. I

My object is further, to provide guiding chutes or aprons on the sides of the car and so arranged that they are moved into inclined position when the body is tilted to dumping position, the said aprons being hinged and operatively associated with the locking mechanism of the doors that said mechanism operates to hold the aprons from swinging outward from the side of the car at all times except when the locking mechanism is being operated for releasing the doors preliminary to or duringthe dumping operation.

My object is further, to provide a dump ing car with side doors hinged at the top and having their lower portions so shaped as to provide a joint with the body which shall present an extended surface frictionally in contact when in closed position to provide a nop-leakable joint.

With the above and other objects in view,

Specification'oi Letters lfatent.

Application filed October as, with. Serial Ito. 56,l36.

the nature of which will be more fully understood from the description hereinafter, the invention consists in the novel construe tion of dumping ears as hereinafter more fully described and defined in the claims.

Referring to the drawings z- Figure l is end elevation, with part in section, of a dumping car embodying my invention, the truck thereof being omitted;

Fig. 2 is a' side elevation of one end of a dumping car embodying my invention;

Fig. 3 is a cross section of my improved car showing the special constructions adjacent to the locking means for the door etc.; and

Figs. 4, 5 and 6 are cross sections of details showing the means of supporting the apron and the locking mechanism for the doors.

2 is the longitudinal girder frame, which is ordinarily supported u'pon the trucks (not shown) and said girder at intervals with rocker beds 5 on its upper part, with which the rockers 4t engage, said ,rockers attached to and supporting the body *3. By this construction, the body may be rocked upon the girder frame and brought into a tilted position to either side of the car, as may be desired, one of said tilted positions being indicated in dotted lines in The body 3 has longitudinal girder irons 17 along its lower outer side edges and similar irons 16 along its upper outer side portions, the space between said girder irons 16 and 17 being open except in so far as it may be closed by hinged doors 15, of which there may be one or more on each side of the car. The bearing 12 carrying a hinge rod 14 upon which the doors 15- are hinged at 13, said doors arranged to swing outward at the bottom during the dumping operation. The longitudinal girder irons 17 at the lower side edges of the body support the flow plates and also carry-the bearing castings or parts 29 in which the rock ghaft 23 is journaled, said shaft operatively'Ecarrying the latch hooks 24 for engaging the doors when they are to be held in closed position. As shown, these irons 16 and 17 an L-shaped in cross section, but I do not confine myself in this respect.

The body 3 has its ends at the middle than at the sides adjacent to the girder irons 16 so that the load may be girder iron 16 is provided with greatly higher frame is provided heaped u at the longitudinal middle porunderstood that this is not essential, as it will 'sufice to here the ends extend sulfiyided with inwardly extending wings 21 the by suitable lugs 30.

cicntly above the doors for the purpose with outlevel1n1g ed the outer upper portions foneppeersnce, as has been done in the particular illustration of this application. In those cases where there are :1. plurality of doors on each side to be employed, the body may be divided transversely by division plates or partitions 8" to be arranged intermediate of adjacent doors so that the opening of a door will cause only s portion of the whole load to be discharged. These partitions are riveted both to the fioor and to the upper girder irons 16 and set us braces to ti. em and the door supports.

The door. 15 may have their ends prowhich act as side guides for the discharging contents. When the doorsere permitted to slwmg outwardly, sir-1d wmgs'extendmg down close to the floor plates are curved to maintuin this relation durin the normal action of the doors. It will o further observed that the lower edges of the doors are bent izglfangend braced by bracket portions 22 1g. inwardly directed portion there is secured a special U shaped portion 18 which greatly strengthens the lower edge of the door and further provided an inclined lower seating flange 19, whose inner portion elines with steral edge of the floor plate and whose outer portion inclines downwardly and outwerdly and preferably slightly tangential to a curve about the hinge rod 14 as a. center. Riveted to this lower portion 18 of the door and preferably located adjacent to the middle of its length, is the latch frame 20, desirably formed of a casting and having a suitable hole through which the look or latch book 24- passes for engagement when lockmg the door in closed position (Figs. 1 and 3). is a longitudinal sill plate bolted at 39 to the bearing brackets 29 (which are riveted to the girder iron 17) and having Its upper part inclined inward toward the girder iron 17 and held in position thereto This Slll plate 30 presents an inclined surface against which the tan ential portion 19 of the door makes close our ace contact to form a tight or non-leaking joint when the door is closed. The tightness of the joint at the bottom is supplemented by the use of the wings 21 on the ends of the doors, they forming close fitting ports around which the contents of the car can not work. It will thus be seen that this construction of door is very efiective for It will also be seen that to this masses,

use where the load is of subdivided or loose material such as sand, dirt, marl or other substance in a line state of subdivision. It will also be noted that the sill plate 30 is removable, so that it may be replaced when worn. When the door is closed the weight thereof will cause the port 19 to seat positively upon the sill plate 30 and no normal wear of the hinges of the door will interfere with the tightness of the joint thus provided.

23 is :rlongitudinol latch operating shaft journeled in the bearing brackets 29, and has at its end a lever 41 by which it may be rocked by hand; and said lever is also provided with a special shaped slotted arm, the slot of which comprises the parts 44, end 46, as clearly shown in Figs. 5 and 6. The slot ports 44 and 45 form abutment socks-ti; for a pin 43 of a toggle lever d2 and the port 46 forms as communication between said psrtsst end it? whereby the pin may be transferred from one purl; to the other, as shown in these figures.

The toggle-lever 42 is hinged at d0 to the free end of the toggle lever 41- which letter has its. other end hinged to the main or. girder frame 2 st 48,- (Fig. 1.) When the our body is in its horizontal or non-dumping position the toggle levers ll and 42 are suspended as shown at right side of Fig. l; but when the body is tilted into dumping position as shown in dotted lines, the toggle levers at the rising side open out to provide the reach to maintain connection with the lever 47, while the toggle levers on the dumping side form a strut to automatically operute the lever 47 and rock the shaft 23 to release the doors on the dumping side. In doing this, the angle toggle bar 41 comes into contact with the girder frame 2 and thereafter the bar 42 acts as a radius bsr hinged at u'fixcd axis and hence operates as a. strut to force the lower end of the levhr l7 outward and rock the shaft 23 as will be readily understood. When the doors are to be automatically unlatohed for dumping" during the tilting operation the pin 43 is adjusted in the slot 44 as shown in s. l and 6. as in that case the greatest oscillation is given to the lever 47 and rock shaft 23. On the other hand, when the doors are to be released by manual operation, the pin 43 is adjusted into the slot 45 as shown in Fig. 5. us in this case only a partial oscillation of the lever 47 and roclr shaft 23 is required and then only to release the latches 24 and the aprons 25, whereby the former may be lifted by hand and the latter automatically oscillated into inclined position as shown in dotted lines in Fi,. 1.

The rock shaft 23 1S fitted with the latches 24 in such manner that they are rotatable through a. given are and this is provided by them having slots 28 in their hubs into which lull outed in. the latter the and. nuts oil the bolts 27 extend, sold bolts passing through. end iriovinp; with the rock *ilfifi} (Figs. 5 and It will be seen from Fig. 5 that the latch 24% may be lifted ut its book end in the act of re leasing or unlocking the door by hand, Whereus in udjiustmeut shown in Fig. 6 the door would be unlocked automatically by eh oscillation of the rock shaft during; the tilting; oi the cor-bul y. the rock eheit being given so grc L lletion that the bolt 27 will strike tl e opposite ends of the slots 28 end positively oscillate the latches ustment shown in Fig. 5 the 2%. In the ad tilting of the body will notmore the rock shaft sufficiently to cause the latch 24: to be raised automatically. By this capacity for either automatic or hand releasing of the doors, it is possible to dump the entire con tent of the body at one operation, or only dump the content of a single compartment from one door passage us desired.

The apron 25 has loin e ports by which it is suspended and Lilla/mid ports are journeled on the rock shaft as shown in Figs. 3 and 4. The hub ports 26 have slots 28 corresponding to the slots 28 in the latches and the rock shaft 2 has bolts 27 whose heads and nuts extend into the slots and Age the ends thereof. When the our body iorisontul. (Fig. 3), the apron rests upon the spring" stops by which it is pre Venteo from swinging inwardly; and. it will also be observed that the ends of the slots 28 abut against the bolt heads 27* on the rock shaft 23, so that the apron cannot swing outwardly during the transportation of the car so long us the rock shaft is locked against rotation. In this way the apron is held in d fixed position. lin practice, the rock shuilt23 is normally held in the position indicated by the hand lever d7 being frictionully locked by 7; and 2). This spring made of a piece of flat spring steel provided with a shoulder back of which the leversnaps When the upper end is pulled outward, and by which it is held with suilicient friction to normally retain its locking position. Any other suitable lock or latch may be emnloyed for holding the lever in position. it will be understood that when the lever l? is rocked by the mechanical devices herein before described during the tilting operation of the body, the rock shaft 23 Will be shifted from the position shown in Fig. 6 to the position shown in Fig. 5, if the pin 43 is in the socket portion 45 as indifigure, and to a greater extent if said pin is in the socket 44, and in either case the apron 25 is released so that it may be moved out into an oblique position as indicated in dotted lines (Fig. 1). This latter action takes place Whether the body is to be automatically dumped by the autothe latch spring 47 metic operation of the latches 24 (by ad.- justment of pin e3 shown in Fig. 6) or is to be manually dumped by bond operation of the latches (when the pin 43 is in the adjustment indicated in Fig. 5), for in eitl'ler case the apron performs the some function.

it will now be apparent that l have devised a novel and useful construction which embodies the features of advantage enumerated {is desirable, end while l have in the present instance shown and described the preferred embodiment thereof which has been found in practice to. give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification in. various particulars without departing from the spirit or scope of the invention.
